Volume loss as a tool to assess kiln dryingof eucalyptus wood

Abstract: In this study, we aimed to analyze the kiln drying quality of Eucalyptus grandis, Eucalyptus saligna and Eucalyptus dunnii woods with respect to volume loss. Wood from the three species was kiln dried together with the same drying schedule and conditions in a conventionaltemperature pilot kiln. Three kinds of volume loss were evaluated: total -from saturated (initial) to machined (final) condition; shrinkage -from saturated to 10% moisture content; and machining -from 10% moisture content to machined condition… Show more

“…These findings concurred with the results of Stangerlin et al (2009) and Braz et al (2015). However, in the case of the removal of the adsorbed water below the PSF, the drying rates remained very close in both regions, displaying no statistical difference; thus clearly indicating that, below the PSF, it is the intrinsic characteristics of the wood which control the drying rate (Batista et al, 2013;Redman et al, 2012). According to Braz et al (2015) the factor wood density exerts a negative influence on the drying rate, causing the wood drying rate to slow down.…”

“…Esse tipo de secagem é utilizado muitas vezes como pré-secagem ou secagem parcial, sendo a fase final feita em estufas, como também para secagem completa, dependendo do seu uso (Ponce & Watai, 1985). Batista et al (2013) ainda complementam que a secagem ao ar, além de reduzir o tempo necessário para a posterior secagem artificial, também pode reduzir a incidência de defeitos normalmente observados nas fases iniciais do processo.…”

“…Santos (2002) recomenda para E. grandis temperaturas variando de 40 °C a 65 °C e potenciais de secagem de 2,0 a 2,7. O programa utilizado por Batista et al (2013) para secagem de E. grandis, E. saligna e E. dunnii, com temperatura inicial de 40 °C, temperatura final de 66 °C e potencial de secagem no ponto de saturação das fibras de 2, é simular aos definidos nesse trabalho para outras espécies. Da mesma forma, Travan et al (2010) utilizaram temperaturas entre 45 °C e 70 °C ao longo da secagem de E. grandis e E. trabutii.…”
